“The use of pulse oximeters has been very useful during the COVID-19 pandemic once someone has tested positive,” adds Dr. People on home oxygen should have one, she says, as well as infants with certain types of congenital heart disease, infants and children with tracheostomies or those on home ventilation.

Atkins, M.D., chair of the American Heart Association’s Emergency Cardiovascular Care Committee based in Iowa City, Iowa. “Pulse oximeters are most useful for persons who have lung and heart problems, which can cause abnormal oxygen levels,” says Dianne L. Meanwhile, OTC pulse oximeters are not FDA regulated and are sold directly to the consumer online and at pharmacies. Prescription oximeters must pass FDA inspection for quality and accuracy, and are typically used in a clinical setting-you need to have a prescription from your doctor for home use. Pulse oximeters are available as a prescription or over-the-counter (OTC). Some can connect to a smartphone app for easy recording, data storage and sharing with your healthcare team, which can be helpful for people with chronic conditions or who use home oxygen therapy. They range in price and size and are sold by both brick-and-mortar and online retailers. Pulse oximeters commonly used at home are finger monitors that are small and painlessly clipped onto your fingertip. Reflectance probes measure blood oxygen levels with an emitter and sensor that are placed side by side on a flat body surface with underlying bone (such as the forehead).Transmission probes are used to measure blood oxygen through your fingers, toes and earlobes.If it’s lower than 90%, you should seek immediate medical attention. Typically, an oxygen saturation level is considered normal at 95% to 100%. To calculate the oxygen saturation level percentage, a photodetector reads the light absorption from these two beams of differing wavelengths. When you insert your fingertip into this small device, it uses two non-invasive LED lights-one red (which measures deoxygenated blood) and the other infrared (which measures oxygenated blood). If all of the binding sites on the hemoglobin molecule have oxygen, the hemoglobin is 100% saturated.

Pulse oximetry measures the percent of hemoglobin saturated by oxygen, which is called oxygen saturation and is expressed as a percentage. Oxygen is attached to hemoglobin, an iron-rich protein in red blood cells. Pulse oximetry is a quick and painless indicator as to how well your body is working to move the oxygen from your heart to your extremities.
